LOCK MECHANISM.

Specification of Letters Patent.

Patented Sept. 10, 1918.

Application filed January 25, 1917. Serial No. 144,334.

To all whom it may concern:

Be it known that I, HOWARD E. VAN ORDEN, a citizen of the United States, and residing at East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Look Mechanisms, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to lock mechanisms and particularly to devices of this class commonly known as three-point locks, and the object of this invention is to provide an improved device of this class which is simple in construction and operation and adapted for use in connection with doors of any kind or class and of any construction.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which 2-- Figure 1 is an inside view of a part of a door frame and indicating my improvement applied thereto;

Fig. 2 a partial section on the line 22 of Fig. 1; s

Fig. 3 a partial section on the line 3-3 of Fig. 1 on an enlarged scale;

Fig. 4; a partial section on the line H of Fig. 1 and on an enlarged scale; and,

*Fig. 5 a partial section on the line 5-5 of Fig. 2, on an enlarged scale and indicating the operation ofone of the lock mechanisms.

In the drawing I have indicated at a a part of a sheet metal door and at b a part of a sheet metal door frame. In the practice of my invention, I provide a lock mechanism of the class described consisting of a plate 0 having a central enlarged portion 0 and a bar (Z is slidably mounted on said plate and through suitable guide keepers 0 secured to the .plate 0, said rod being provided with a central raised portion 0Z and corresponding raised end portions d I also rovide a plurality of boltse, c and 6 t e bolt 6 being pivoted to the central raised portion (Z of the bar (2 by a screw 7", while the bolts 6 and c are pivoted to the raised end portions 01 of the rod d by screws F. The outer end portion of the bolts 6, c and e are provided with elongated apertures e through which pass screws 6 which are secured to the raised sheet metal plates 9 riveted or otherwise secured to the plate a, and said screws e and apertures 6 form guides for the bolts 0, e and 6 The outer ends of the bolts 6, c and c are adapted to operate in connection with a latch or similar plates h secured to the door frame I) in line therewith, as clearly shown in Figs. 1 and 5 of the drawing.

The bolt 6 mental plate 11 having an elongated aperture 01 Mounted on the screw 7" is a disk or roller i which is free to rotate thereon and which operates in the elongated aperture in the plate 11, and mounted on the screw f out wardly of the roller i is a lock plate j composed of two cylindrical parts 3' and 9' the part j operating in connection with the screw f while the part 7' is mounted on a screw or pivot pin is secured to a raised plate on which is riveted to, or otherwise secured to the enlarged portion 0 of the plate 0 and which forms a part of a lock casing.

The part j of the lock plate 3' is provided with inwardly directed finger pieces j and an outwardly directed stud 9' having wings or ears 9'. Mounted in the door a, and the enlarged portion 0 of the plate a is a suitable cylinder lock mechanism a operated by a key in the usual manner, which is not shown, and connected with the rear end portion of the cylinder of said lock mechanism is a plate n having inwardly directed fingers n which are adapted to operate in connection with the wings or cars j on the part j of the lock plate j, of a'key into the lockm, and the rotation of the cylinder of said lock will move the fingers n to rotate the lock plate j which, in turn, swings the part 7' of said 1001: plate on the screw or pivot pin 74 from the position shown in full lines in Fig. 5' to that shown in dotted lines in said-figure, which operation raises thebar d and moves vthe bolts 6, e and c inwardly, or out of engagement with the latch plates h in the door frame as clearly indicated in Fig. 5. 7

The above operation of moving the bolts 6, e and c inwardly may also be accomplished from the inner side of the door, by grasping the finger pieces 9' and rotating the part 9' of the lock plate j in the same manner as said plate is rotated by the lock mechanism 1.

The raised plate m which forms a part is provided with a supple whereby the insertion of the lock casing is provided with areshaped apertures m in which the fingers n operate, as clearly indicated in Figs. .1 and 4 of the drawing.

When the bolts 0, e and e are-inthe position indicated in dotted lines in Fig. 5, the same may be moved outwardly by the rotation of the cylinder of the lock mechanism by a key in the usual manner, or by rotating the lock plate j by hand, or'by grasping the finger pieces j as will be readily understood, and the downward movement of the bar (Z to bring the bolts e, 6' and 6 into their operative position is limited by the guide keeper 0 below the lock H mechanism, as clearly indicated in Fig.3 by

the central raised portion d striking the 1 same.

' My invention resides in the bar Jar a single element'having a plurality ofbolts pivotally connected therewith and suitable means for operating the bar to projecta'nd withdraw the ,said bolts to lock or open a" door of any kind or class, the invention being not limited .to any specific. form of lock mechanism for accomplishing this result, and changes in andmodifi'cations of the construction herein shown and described may be made, within the scope of the appended claims, without departing from the spirit of my invention.

WVhile I have shown my improvement applied to a sheet metal door and door frame and without an inclosing casing of any kind or class, it will be understood that the entire lock mechanism maybe inclosed in a suitable casing, or the central-portion of sald mechanisminclosed, if desired. 7 v

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. Adoor lock of the class described, comprising a bar movable longitudinally of the door, lock bolts pivoted directly to said bar j 2.'In a door lock of the class described, i a lock, bar movable longitudinally of the "door, and means rOrepemting said bar con- 3. In a door lock of the class described, a

bar mounted to move longitudinally of the door, a plurality of bolts pivoted directly to said bar, a cylinder lock mounted in said door, a lock plate pivoted rearwardly ofsaid cylinder lockand adapted to be operated by means connectedwith said lock, one of said bolts being provided with an enlarged head portion having an elongated aperture and the free end of said .locl'r'platebeing provided with a part adapted-to operatein said aperture in the movement of said lock plate by said cylinder lock' to move said bar longitudinally of the door and to move said bolts inwardly and outwardly, and I means 'for guiding said bolts in their movement.

4. Inv a door locksof the class described, a bar mounted to move longitudinally'of the door, a plurality of bolts pivoted directly to i said bar, a cylinder lock mounted in said "door,a lock plate pivoted rearwardly of said cylinder lock and adapted to be operated by fmeans connected-withsaid lock, one-of said bolts being provided with an enlarged head portion having an elongated aperture and the free end of said "lock plate being provided" with a part adapted to operate in said aperture in the movement of said lock plate by'said cylinder lock to move said bar longitudinally of the door and to move said bolts inwardly and-outwardly, :means for guiding said bolts in their movement, and

means for operating said lock plate independent of said cylinder lock to move said bar longitudinally of the door to move said bolts inwardly and outwardly.

In testimonythat I claim the foregoing as} my invention I have signed my name, in presence of the subscrlblng witnesses, this 24th day of January, l917. 7
